By Charlie Self

Dust masks and air cleaners are on the list of necessary tools in most shops, but research shows that some woods are more dangerous than others. Most woodworkers realize that over time, wood dust can cause many of the same lung problems as asbestos. But some woods have developed their own protection against insects, microbes, fungus, and even other competing plants.

Not every person responds to these woods the same way, but the attached chart highlights some woods that you might consider taking more precautions with. Sawdust irritates a person’s respiratory system, but some woods, such as willow, can actually cause nasal cancer!While most of the reactions on the chart are caused by the wood dust, a few are confined to jus the bark and leaves. At the other end of the spectrum, contact with the actual wood of some species can cause extreme reactions. Those woods are usually the more exotic tropical hardwoods, such as rosewood, padauk, and teak, but sassafras (a relatively common found wood) can cause breathing problems, nausea, or even cancer.
